New damage formula: weapon bullet dimensions (in millimetres) multiplied by each other, and divided by two. For example, 5.56x45mm NATO: 5.56 multiplied by 45 divided by 2 = 125 (rounded to nearest whole number). For energy weapons, it's clip size (always 100) multiplied by ammo use, divided by 4 (or 6 if it's powered by small energy cells). Since most guns in real life kill with a shot to the chest or torso, this system is quite effective at making the game feel very realistic.

Improved needs system: Obsidian at least had the thought to implement this system, however, it doesn't fit what I feel Reborn needs in the way of a harsh, but fun system. The system timing will be changed, and an optional piss/crap system will be implemented. On top of that, the effects will be more dramatic.
